Question

Plant cells involved in secretion and absorption of solutes are
a. Glandular cells
b. Transfer cells
c. Active cells
d. Junction cells

Answer 1

While individual plant species are unique, all share a standard structure: a plant body consisting of stems, roots, and leaves. all of them transport water, minerals, and sugars produced through photosynthesis through the plant body during a similar manner.

Complete answer:
Detailed studies on the function and development of transfer cells within the context of seed filling are administered mainly in cereal endosperm and for the cotyledon and testa cells of legumes. The main solutes transferred are amino acids, sucrose, and monosaccharides. The contributions of recently identified symporter proteins to solute transfer are reviewed here, as is the role of apoplastic invertases in promoting solute assimilation.
Transfer cell differentiation is subject to developmental control, and should even be modulated by sugar levels. The foremost abundant genes specifically expressed within the transfer layer of maize endosperm encode small antipathogenic proteins, pointing to a task for these cells in protecting the developing endosperm against pathogen ingress.
Glandular cells form special structures called glands and are related to excretion and secretion.
Transfer cells are specialized parenchyma cells. Their inner cell wall has numerous infoldings that help within the secretion and absorption of solutes.
Active cells are rapidly dividing meristematic tissues which differentiate to make permanent tissues.
Junction cells connect various tissues for communication, occurrence, and anchoring of tissues.

So, the correct answer is 'Transfer cell’ (B).

Note: Transfer cells are highly polar in their organization, the characteristic cell membrane ingrowths developing on one face only. The presence of cytoskeletal components bordering wall ingrowths is documented, but their role in establishing transfer cell morphology remains to be established.
